[Intel-gfx] [PATCH 6/8] drm/i915/gen9+: Add has_ipc flag in device info structure

[Mahesh Kumar]

From: "Kumar, Mahesh" <mahesh1.kumar at intel.com>

New Isochronous Priority Control (IPC) capability is introduced in newer
GEN platforms. This patch adds a device info flag to indicate if platform
supports IPC. Patch also sets this flag in supported platforms.
